Astell&Kern AK380 overview

  • 1Description

The Meteoric Titan AK380 Portable Hi-Fi Audio System from Astell&Kern is a media player and USB DAC that supports a wide variety of audio formats including WAV, FLAC, ACC, MP3, WMA, OGG, and more in addition to DSD. It is equipped with a dual DAC AKM AK4490 chip that allows for native DSD playback, meaning it does not need to convert DSD files to WAV prior to analog conversion.

The AK380 can be controlled via its 4.0" WVGA touch screen and features a physical volume knob. The unit has 256GB of internal storage, and supports microSD cards up to 128GB, for a total of 384GB of potential storage. Thanks to its streaming capabilities, you are not limited to playback of songs you have on your device, as it can stream tracks from your Mac or PC connected to the same wireless network.

32-bit 384 kHz Bit-to-Bit Playback
  • All of the AK380’s circuit design, including the digital-analog converter (DAC), is ready for 32-bit processing to handle 32-bit music natively
  • The result is the AK380 plays up to 32-bit, 384 kHz, any 24-bit music files, or double layer DSD 5.6MHz natively, without down sampling, conversion, or compression
PEQ (Parametric EQ)
  • A parametric equalizer (PEQ) was implemented in the AK380 to deliver detailed adjustment of the original sound, and an audio digital signal processor (DSP) was added to aid in this process
  • This frees up CPU cycles previously needed for calculating graphic equalizers (GEQ), allowing more detailed and accurate calculations via the dedicated DSP
  • The audio DSP expands the existing 10-band, ±0.5 dB graphic equalizer (GEQ) to 20-band, ±0.1 dB to more precisely adjust the frequency and gain (dB) as well as more accurately specify the frequency range via Q value adjustments
  • 20-band PEQ frequency values
    • 30 Hz
    • 45 Hz
    • 60 Hz
    • 90 Hz
    • 120 Hz
    • 180 Hz

    • 6 kHz
    • 8 kHz

    • 14 kHz
    • 18 kHz
Equipped With a Femto Clock to Deliver True Original Sound
  • Astell&Kern implemented a voltage-controlled crystal oscillator (VCXO) high-precision clock with a reference jitter value of 200 femto seconds
  • Femto clocks are commonly used in high-end audio systems, and the clock is measured in high-precision femtosecond units (one quadrillionth of a second)
  • The AK380 utilizes a VCXO, or a voltage-controlled crystal oscillator, is a type of crystal oscillation device that creates oscillation frequencies. External environmental stimuli, which in this case mean voltage inputs, influence the frequency value. Adjustments to the voltage input tunes a precise frequency value
  • By utilizing a femto clock, the AK380 is able to create a more accurate frequency value and make fine jitter corrections. As a result, the AK380 faithfully reproduces analog sound closer than ever to the original source when transmitting a digital signal as an analog signal


AK Connect App
  • Astell&Kern has further enhanced DLNA functionality via the AK Connect app
  • Wireless networking DLNA (version 1.0) connects to a NAS or PC, and is easily controlled with a smartphone or tablet through AK Connect
  • Source files on a PC or NAS can be freely transferred and streamed without the hassle of turning on the computer and physically connecting with a cable
  • If on the same access point (AP) network, music files on a PC or NAS can be played back via DLNA
  • DMP (Digital Media Player): Finds a list of content on a media server for selection and playback
  • DMC (Digital Media Controller): Finds a list of content on a media server and establishes a connection to a playback-capable device (renderer). By default, a DMC establishes a connection between a media server and media renderer and controls content playback-related operations
  • DMS (Digital Media Server = Network Server): Actually stores the media content to be shared. When connected to a network, the DMS transmits/distributes the media content for other devices to stream or download
  • DMR (Digital Media Renderer = Network Player): Connects to a media server via media controller for content playback
Pressure-Sensitive Metal Capacitive Touch
  • The AK380 utilizes a metal capacitive touch interface. The pressure-sensitive Metal Touch home button responds to fine pressure changes so users operate the device with just a light touch on the metallic pad
More Expandable Options
  • The AK380 offers great expandable options through its micro USB connection and balanced out ports on the bottom of the unit
  • The AK380's functionality is expandable by connecting to a variety of devices
    • You can increase the output and connect to a greater variety of high-impedance professional headphones through the optional AK380 Amp
    • The optional AK380 Cradle features balanced output in addition to USB data transfer and charging capabilities
    • The optional AK380 CD-ROM drive rips audio CDs directly to the AK380
Design Concept
  • The AK380’s design was inspired by “light” and “shadow”
  • While the design of the AK240 captured a moment in time of light and shadow, the AK380 is designed to express the change of time with more angles on its body. You will notice the different angles on its surface as you view the AK380
  • Astell&Kern believe that the beauty of the design shall reflect what the AK380 can do with music. As different angles of light casts different shadows, different music will give you a variety of emotions

    Astell&Kern AK380 reviews

    AK380 Portable Hi-Fi Audio System (Meteoric Titan) is rated 2.3 out of 5 by 4.
    Rated 1 out of 5 by from Don't Buy this product!!!! I bought this product a short time ago. It failed after 1 day. It is as dead as a doornail. I have been trying to contact iRiver (Astell and Kern) regarding a replacement or repair and they have refused to respond to all my efforts. The product doesn't work and the manufacturer won't stand behind it!!!!

    Rated 5 out of 5 by from Crazy expensive but still worth it. Build like a tank. The build quality of this Portable Audio Player is second to none. The quality of the leather case has to be seen to be believed. There are some nice inclusions in the box like the case and screen protectors (2 of them each). It's a heavy piece of quality audio kit with a simple and uncluttered user interface. I'm so glad that Astell and Kern did away with all the typical smart phone apps in this player and stayed focused on the primary use of it being an audio player. The headphone amp has plenty of output power with the emphasis on a clean dynamic sound without coloration and no low level noise at all. Works great using the line output into an external amplifier. The perfect example of what a high end Audiophile product should deliver. Partnered with the amazing Jerry Harvey Roxanne II's in ear headphones (which I purchased along with the AK380) and you'll be blown away by the sound. I like the idea that you can add on accessories like the AK Recorder and AK Cradle. The AK Recorder allows you to record Analogue sources at DSD quality as well as Digital sources. On the one hand I would have preferred the equaliser to have a greater range than just -5db to +5db but then on the other hand I found that I didn't need to make any adjustments with the Roxanne II's however with other headphones I would have liked a greater range, perhaps....... The jury is out on this one. If you're an Audiophile person then jump straight in and get one.

    Rated 2 out of 5 by from Ak380 I don't know what is the all fas about it sounds lean and slow I'm an audiophile ho wonted to go into portable audio but it is still not there not even close I don't know ho write the review about this things but I feel as if they have never heard high quality gear and how music should really sound like That is really sad people are paying this amount of money for such an low grade gear.
